Amos' mobs
by Amos
Amos' mobs is a NeoForge mod for Minecraft 1.21.1 that adds mobs based on community concept art and abandoned ideas from the game's history.
What it does
Amos' mobs collects concepts that the community proposed and that were drawn but never fully built into Minecraft. The author chose abandoned ideas, especially mobs, that fit the existing themes of the game. Two early additions are the Growly jacket and the Warm coat, and more creatures are planned.
Development is handled by a single developer who is still in high school and is learning Java, so the pace is slower than a team project. The author reports that early betas had many bugs and holes before the first beta release, and that clean versions are a priority from here on. Geckolib is required, and Curios API is optional. The mod is published for NeoForge on 1.21.1 with the 0.0.3-alpha file from 2026-09-16, and runs on client and server. It is released under All rights reserved and is not open source.

Planned mob count
The author expects the final release to contain at least around 60 mobs, with development slowing down after that point.
Ongoing ports
New content is ported to newer versions after its first release, so the mod keeps receiving updates.
